ALAL include biologically diverse leukemias that fail to show commitment to either the myeloid or lymphoid lineages or show evidence of commitment to more than 1 lineage.1-3 Cases in the former group are referred to as acute undifferentiated leukemias (AUL), whereas those in the latter are identified as mixed-phenotype acute leukemias (MPAL). One of the major challenges in the subclassification of ALAL in general and MPAL in... References 1.Arber DA, Orazi A, Hasserjian RP, et al.
